Samsung 20S // 18650 2000mAh 30A


This product is unavailable

"...hardest hitting 18650 right now, beats HB6 and VTC6A.

Bottom Line: This is a great performing cell. Until now the only 30A 18650’s we had were the 1500mAh LG HB2/4/6. The Samsung 20S not only has increased capacity over those cells but it performs MUCH better too, giving us a lot more vaping time at high current levels.

It hits harder than any other 18650 down to about 3.3V and appears to have a true 30A rating.

At lower current levels, under 20A or so, there are better higher capacity choices. But at 30A the Samsung 20S is the clear winner. In the 20A-30A range it is a close race between the 20S and the VTC5A/5D/6A. You’ll have to test them to see which performs better for the way you vape.

I don’t have the datasheet yet to know Samsung’s ratings but I am estimating them to be 30A continuous and 2000mAh. If needed, these ratings will be adjusted once I see the datasheet." - Mooch
